An object of the invention is to provide an improved adjustable guard for openings adapted to prevent entrance into a window `i5 opening or to preventpdamage -to the frail wire screencommonly used on screen doors. vAnother object is to provide a metalllc guard which shall be so constructed as to `be adapted to be readily adjusted without ne- 2o cessitating the use of a tool or xtools, and which shall permit thepassageA of light and atmospheric air with no serious obstruction .e through it when in place. 1

A further object is to provide an adjusti `25 able metallic guard for openings which shall be of suoli construction as to be adapted for inexpensive manu-facture and yet be strong, durable and economical in` use. With the above-mentioned and other ob- `30 jects in view, the invention consists in a novel 40 ings,-Figure `1 is a front plan view vof the 'improved guard in which one portion is shown as when contracted in one direction and expanded in another direction, the remaining portion being shown as when elon- 5 gated in one directionand contracted in another direction; `FigfQ isareproductionfon an enlarged scale ofa portion offFig, 1` and e havingportions cut away todisclo's working parts g` Fig. 3 is ain enlarged fragmentary section, as nthe line XXon Fig. l whichV 50` indicates a division oftwo` portionsofthef guard that are differentlyy adjusted; 4 is a fragmentary section onran enlarged scale showing lower portions of Fig. 1; and Fig. is` a perspective' view ofa section of each oneo-faplurality'of extensible or contracti` i e fable frame rails embraced" 'in `the invention. Y which shall be of such construction as to be Similar reference characters in the diiferent figures of the drawings indicate"Cerre-` sponding `elements or `features of Aconstruction herein. referred tomin detail. e e A practical embodiment of the invention `comprises `two sectional frameside rails `A` and B which in practice are usually arranged horizontal'lyand has upper andlowerrails 65 respectively; and twoysectionalend rails C and D which in practice are usually vertical. Y The` rails are composed of suitable" Vsheet metal, andall the rail sections aresubstantially' alike except as to dimensions. The rail sections may be variouslyconstructed as to f details conforming tothe conception of invention that each rail Vsha-ll be longitudinally adjustable and adjustably hold parts of adjustable lattice-work. e "As preferably constructedeach rail `has an outer section comprising a`v` base or back` e plate l, acurved face portion 2 continuing from the base plate," a guidebar portion 3 extending inwardly or backwardly 4under the curved portion intermediately-between it and the base plate. fEachrail has also a` similar inner section comprisingla base plate l', curvedface portion 2 and a `guide bar 'portion 3.` The inner section is longitudi- 85 .nally' shiftable within the outer1 section 'and the sections are `frictionally held together. Une end portion of each outer rail section preferably has an ear 4 thereon, each inner rail section having an ear 4 on one end there- EQ of, and each ear has a pivot hole 5 therein receiving a hollow pivot 6 whereby two ears are pivotally connected together, the ear of an outer section being connected to the ear of an inner section, as preferably arranged. Preferably also each ear has a perforation 5 to receive a securing screw or nail whereby to secure a guard to a structure.

A suitable lattice is provided which comprises cylindrical cross bars 7 and 7 which preferably are composed of drawn steel wire and woven together as in making a screen, each bar having an end portion loosely arranged between a guide plate l and an opposite guide portion 8 and having also a crookv .8 that extends about the edges of the guide bar portion and into the space between said portions and the face portion of the rail sections, most of the lattice bars `being so con-V nected with the side rails and a number of them with the end rails as to be shiftable therein. .The lattice bars are oppositely 0E- set at their crossing points 9, so that during adjustments slight pivotal movements occur at the crossing of the bars while the crooks are shifted in the rails.

In practical use, the dimensions of an opening, or of a screen door frame being given, the guard frame is adjusted thereto by applying slight force or jarring longitudinally to the side frame rails until the end rails are spaced apart as may be required, after which the frame is secured in place by means of fasteners inserted in the hollow pivot 6, or in the perforations in the ears. When fastened in place the guard protects the open ing where applied against passage of animals and other depradators through the opening, and eifectually protects screening of ventilating doors against rough 0r careless treatment or abuse of those using the screen doors.

What is claimed is:

l. An adjustable guard including a frame comprising two side rails and two end rails having each an outer hollow section and an inner hollow section shiftable therein, each section being open at one side thereof and having an inwardly extending guide bar on one side of the opening, one end of each outer section being connected to one end 'of an inner section, and oset interwoven wire lattice bars extending loosely into said openl ings and having each a crook shiftably guided on one of said guide bars.

2. In an adjustable guard, the combination of a frame rail comprising a section having a flat base plate and a continuing face Vportion provided on its terminal edge with an inward-extending guide bar portion arranged opposite to said base plate, the bar portion being narrower than the plate; and a wire lattice comprising interwoven bars having ends guided on said base plate and provided with crooks extending loosely lUU llU
